When smgr (found out I had the wrong mgr) displayed the [!!] icon before,
the message I got was that phdaemon died because SOMETHING was swapped
out, either phdaemon or a program it was monitoring.  This time, smgr
quit completely right after the [!!] icon appeared.  From ps, I could
see that the system load was real heavy.  This doesn't assure that
swapping was the cause, but that would be my best guess.

What is the difference between a process being swapped out and normal
VM paging?  I thought the UNIXpc could only support 4M or virtual memory,
but when I formatted the drive, it reserved 6M of space.
